Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- The MCU current consumption is 400uA typically at 3 .3V and 2MHz oper ating clock rate.
- Standby current is 1.5uA at 32kHz clock, and less than 1uA at sleep 16k Bytes OTP for program storage, 256 Bytes SRAM for data storage Low OTP programming voltage , can replace external EEPROM Flexible battery voltage detection range.
- Support grey scale adjustment Every digital I/O port contain Schmitt trigger input and selectable pull up resistor Low voltage detection and power on reset circuit Operating voltage range: 2.4V~ 3.6V Operating temperature range: -4.
- Operates at 3.3V supply and internal RC oscillator frequency , the total typical operating current is 1.6mA.
- The OTP can be programmed in situ and the 2.4V~3.6V programming voltage is generated internally.
- Electrical Specifications（VDD=3.3V, TA=25℃）** SDIC Microelectronics Rev.
- 3． The charge pump driving capability is related to the choice of capacitor and the operating frequency. **Figure 4.

Engineering review checklist
- Confirm repetitive reverse voltage, average forward current, surge current and leakage at the intended temperature.
- Check forward-voltage loss and reverse-recovery behavior at the actual current and switching frequency.
- Review package thermal resistance, copper area, polarity marking and transient derating before layout release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
